The Royal Borough of Kensington and Chelsea believes that cycling can and should mix safely with other traffic. On the left is a picture of the space for cycling just by the Millenium Bridge, along Queen Victoria Street. It's not in Kensington and Chelsea, I admit, but I feel it's a good representation of what a safe mix of cycling with other traffic actually looks like in London. Basically, on your bike, you'll just have to fight the law of the jungle and try and outwit those more powerful, faster, more dangerous, highly polluting motor vehicles on your little old bicycle.

And it could all be so different. Here's Admiralty Arch by Trafalgar Square. Notice the bollards and the segregated cycle infrastructure. This is the exact opposite of a safe mix with other traffic.

All too often, it's really the junctions that hold up people's ability to cycle through London. Junctions and bridges, actually. Just look at the map of cycle casualties in London here (all casualties from 2004 - 8) and you'll see clusters of casualties on bridges or on the approach to junctions. Have a look at the area around Oval station, for example. Or Vauxhall. Or the north side of Blackfriars Bridge. Each red dot is a cyclist death. Each blue dot is a serious injury.

But then they simply wimp out by telling us there isn't space. Look at London's streets, in particular at its junctions. There's plenty of space. But no-one's got the political nerve to actually reallocate some of the four lanes for motor vehicles that come off Blackfriars Bridge, for example, and make the space calmer, slower and easier to cycle through.

Which is why I suspect the Mayor will simply wave through the Kensington and Chelsea transport plan and agree with the royal borough that is not practical to allocate road space specifically to cyclists. It is perfectly practical. The Mayor even acknowledges this is something London needs in his written answer to Jenny Jones. But I, for one, don't believe the Mayor or his transport authoritity TfL have the political nerve to do it.
